' Specification'of Letters Patent.

Application filed se ame 15.1913. 8 Serial No. 789,765."

To all whomfit may concern: r 4 Be it known that I, AUeUs'r LAsoHrNsKr,

a citizen of the United States, and resident of Milwaukee, in the county of Milwaukee and State of 'Wisconsm, have invented new and useful Improvements in Automatic Railway-Brake Controls, of which the fol lowing is adescription, referencefbeing had to the accompanying drawings, which area part of this specification.

' This invention relates toimprovements in automatic railway brake'control.

It is oneof the'objects of the present invention to provide an automatic railway brake controlxin which the brakes of the railway train will be applied in the event ofany of thewheels leaving the-track, thus stopping the train'in time to prevent further derailment and damage.

A further object of the invention is to provide an automatic railway brake control which is of simple and strong'construction, is easily applied to a car and is positive in its action.

With the above and other objects in view the invention consists of'the improved automatic railway brake control and its parts and combinations as set forth in the claims and all equivalents thereof.

In the accompanying drawings in which the same reference characters indicate the same parts in all of the views: Figure l is a side view of a car truck and wheels and a portion of a car with the improved brake" control applied thereto, parts being broken away; Fig. 2 is a vertical sectional view thereof taken on line 22 of Fig. 3;Fig. 3

' is a transverse sectional view of a portion of a car body and the truck thereof; Flg. 4 1s a detail view on a larger scale of oneof; the

levers and connected parts; and, Fig. 5 is a detail sectional view of the air valve and the levers connected thereto.

Referring to the drawings the numeral 8 indicates a portion of a car body, 9 one of the trucks, 10 the wheels thereof, 11 the rails, and 12. the air brake train pipe controlling the application of the brakes to the wheels. As the brakes are of ordinary construction and well known in the art it is not thought necessary to illustrate the same or the air control thereof.

Curved guard members 13 positioned 'on opposite sides of each wheel, ashort distance above the rails, have a pivotal connection 1 1 at their inner ends with holding plates 15 of the levers.

whichare' bolted to the lower portions of'the trucks. "The free ends of the guards curve upwardlyfand'thecurved (ends 16 of the outer guards extend over and rest upon the ournal boxes 17{ for the wheel axles to hold I the guards elevated above the rails.

Upwardly extending arms" 18 secured medially in any manner desired to the guard members on opposite sides oft-he wheelsare oined together above the wheels as indi cats-d by the numerahlt) and are then diverged to straddle the rock shaft arms 20 mounted on the rockshaft 21which extends transversely across and through the timbers ofthecar body 8. I The upperdiverged por 'tions 22 of the arms 18 are provided with bolt openings 23 to adjustably receive the bolts 24: which extend across the diverged portions to engage the'serrated lower edges 20 of the rock shaft arms 20. The portions 1 of the rack shaft arms 20 straddled by the arms 18 are recessed or of less thickness than other portionsto form shoulders 25 to prevent the arms 18 from slipping off the ends The rock shafts 21 above each truck are connected togetherby connecting bars 26 which are pivoted to arms 27 also mounted on the rock shafts 21. The 1 air pipe 12 is provided with a plug valve 28 having a controlling lever-29 which is con- ,nected to one of the rock shafts 21 by a link 30 and a lever arm 31. p The opening 32 of the valve is positioned to normally close the opening to the air pipe,

so that the compressed air in the pipe will hold the brakes in disengaging position but the rails would be engaged by the guards Upon the opening of the if any of the wheels should leave the rails valve the airwill escape and'the brakes will be automatically applied and the train stopped to prevent seriousidamage.

From' the foregoing description it will be P seen that theautoinatic brake control is of simpleconstruction and is well adapted for the purpose desired.

What I claim as new and desire to secure car wheel, and meansconnecting the'guard members to the valve to open the valve and apply the brakes when the wheel leaves the an automatic brake control therefor, comprising a car-air-brake-pipe having a valve, guard members pivotally connected to the car truckand extending on opposite sides of a car wheel,.upstanding arms projecting from the guard members, a rock shaft mounted above the guard membersand provided with projecting-arms one of which is engaged by the upperends of the upstanding arms, and means connecting the other rock shaft arm to the valve to open the valve When one of the guard members en-, gages the rail. g

3. In combination with a railway car of an automatic brake control therefor, comprising a car-air-brake-pipe having a valve guard members pivotally connected to the wardly andsome of the members having their endsresting on the journal boxes of the wheels, upstanding arms connected to and' projectingfrom medial portions of the guards, rock; shafts mounted above the guard members and provided with projecting arms some of which are engaged by the upper ends of the upstanding arms, a link connecting an arm of each shaft together, and means connecting an arm of one of the shafts to the valve to open the valve when one ofthe guard members engages the rail. zIn testimony--Whereof,,I afiix my signature, inpresence of tWo witnesses.
